摘　　要：随着通信技术的不断发展,频谱资源的有限性和用户需求量之间的矛盾日益突出,用博弈论来研究频谱分配问题成了近年来的一个热点。文章针对认知无线网络中频谱共享模型,研究了伯川德模型中一次多主的静态博弈,引入了用户信用级度的控制因子,对主用户和次用户的互相选择进行优化分配,次用户在完成租借主用户的频谱资源过程后,根据“使用体验”的实际过程,反馈分值给频谱决策器,频谱决策器根据收到的控制因子参数,对主用户的收益进行相关调节,这样的操作过程可以有效避免主用户无理的哄抬价格,反馈的分值情况也是频谱信道质量优劣的有效参考,一定程度维护了频谱交易过程的公平性,使频谱交易过程更加井然有序,研究借助算法设计和仿真,论证了信用因子对频谱交易过程的影响。With the continuous development of communication technology,the contradiction between the limited spectrum resource and user demand increasingly prominent,using the game theory to study the spectrum allocation problem has become a hot spot in recent years,in view of the cognitive radio spectrum sharing model in the network,Bertrand model is studied in the case of many main static game,introduces the control factor of user credit level,to regulate and balance between the primary and secondary user selection process,a user after renting the main users of spectrum,decision feedback a score to the spectrum,spectrum decision must according to the scores of user feedback,adjust the benefits of primary user,so that to prevent malicious push up prices,the main users of spectrum a real feedback of channel quality,maintain the good order of spectrum trading market,the algorithm design and simulation,to verify the credit level of the main user gains and the influence of the pricing.
